Upload local files (figures, images, any asset) to the user's public CDN at cdn.hails.info (Cloudflare R2) and get back public https URLs. Use when an image/file needs a public URL — e.g. embedding a figure inline in a PRIVATE-repo GitHub PR/issue description (private-repo raw/blob links do NOT render; a public cdn.hails.info URL does, via GitHub's camo proxy), sharing a screenshot, or any "host this so it has a URL" need. Backed by the kb project's R2 scheme.

cdn-upload — public URLs for local files via cdn.hails.info

cdn.hails.info is a public Cloudflare R2 bucket (r2:cdn-hails-info). Upload a file and it is reachable at https://cdn.hails.info/<key>. Because the URL is public, GitHub renders it inline in markdown even for private repos (where committed/raw.githubusercontent.com image links 404 or are blocked by the camo proxy).

Use it

~/.agents/skills/cdn-upload/scripts/cdn-upload path/to/figure.png [more.png ...]
# prints one https://cdn.hails.info/img/<sha256[:32]>.png per file on stdout

The script (mirrors DJRHails/kb bin/r2_upload.py):

Content-addressed: key is img/<sha256[:32]><ext>, so identical bytes collapse to one object and re-uploads are idempotent (same URL every time).
Immutable cache header on upload (Cache-Control: public, max-age=31536000, immutable).
Routing: a local rclone r2: remote if configured; else, inside a gantry worker (the gantry CLI is on PATH and $GANTRY_API_KEY is injected), it runs gantry attach — which POSTs to gantry's /agent/attachments, since gantry holds the R2 creds the sandboxed worker lacks, and returns the same cdn.hails.info/img/<sha> URL (images only); else it scps to trifle (the user's Mac, where rclone + the r2: remote live) and uploads from there. So it works from a maintainer host, a gantry worker, or any tailnet host.

Embedding in a GitHub PR/issue (the common case)

url=$(.../scripts/cdn-upload figures/foo.png)
Put ![caption]($url) in the PR/issue body.
Update an existing PR body with the REST API (avoids a gh pr edit bug that fails on Projects-classic GraphQL): gh api --method PATCH repos/<owner>/<repo>/pulls/<n> -F body=@body.md.

Notes

Verify a URL is live: curl -s -o /dev/null -w '%{http_code} %{content_type}' "$url" → 200 image/png.
The full kb flow (bin/r2_upload.py <dir>) also rewrites markdown image refs in-place and keeps a content registry; this skill is just the upload primitive for one-off files.

cmux-fork-session

DJRHails/dotfiles

Fork the current Claude Code session into a new cmux split pane (or tab) — opens a split beside the caller, resumes this session with --fork-session, titles it 'fork: <name>', and keeps that title. Use when the user asks to fork/duplicate/branch the current session into a new split or tab. Works whether the session is local on the cmux UI host or running on a durable/mosh remote (e.g. bonbon). Requires the macOS cmux app on the UI host — skip if the session was not started from cmux.

cmux-rebuild

DJRHails/dotfiles

Manage the user's durable remote dev sessions — mosh+zellij sessions on a remote host (default bonbon), surfaced as cmux tabs via `ssh::durable`. Load when the user wants to rebuild/resurrect lost cmux durable surfaces after a cmux restart or a mass disconnect, reconnect/sort remote sessions into per-repo cmux workspaces, retitle durable tabs, reap orphaned mosh-servers, or understand the `ssh::durable` picker and its green-● connected indicator. Triggers: 'ssh::durable', 'durable sessions', 'resurrect/rebuild cmux', 'lost my bonbon connections', 'reap mosh-servers', 'the green dot'.

slidesync

DJRHails/dotfiles

Bidirectional sync between a Slidev markdown deck and Google Slides as native, editable objects (not images). Push markdown -> Slides, pull Slides -> markdown, and round-trip. Use when the user wants to author/version a Google Slides deck from markdown, replicate a deck's styling, or keep a .slidev.md in sync with a presentation. Auth is borrowed from the `gog` CLI (no separate OAuth setup). Requires `gog` with stored credentials — currently macOS-only (reads gog's macOS Application Support path), so skip on Linux hosts.
